入侵物种造成严重的生态和经济破坏;然而，其成功入侵的机制往往仍然难以捉摸。以入侵亚洲和欧洲的全球性检疫性害虫松材线虫为例，研究表明，该物种具有高度的竞争能力，促进了其建立和快速传播。为了探索可能解释其高度竞争能力的生物学特征，我们专注于表达表型可塑性，以应对入侵物种B中雌性在其发育过程中所经历的食物条件。拟松材线虫Bursaphelenchus mucronatus。我们报告了一个意想不到的显着差异的表型权衡卵数和卵大小的入侵物种B。木生植物和本地种B. mucronatus这导致了入侵物种在高和低食物条件下培养的优越的上级繁殖能力。这些效应反映了适应性最优资源分配，即在有利的环境中产生更多的鸡蛋，以提高种群的生存能力。此外，我们还证明了B.木虱卵孵化早于B. mucronatuswhen their其parents父母experienced经验high高food食品availability可用.因此，本研究首次揭示了家蚕繁殖性状的表型可塑性。使该物种相对于其本地对手具有竞争优势。mucronatuswhen they are under different range of food availability.这些结果是一个重要的问题，如何外来入侵物种排除本地物种从其原来的生态位的回答一步。
Invasive species cause severe ecological and economic damage; however, the mechanisms underlying their successful invasion often remain elusive. In the case ofBursaphelenchus xylophilus, a global quarantine pest which invaded Asia and Europe, it has been suggested that this species possesses highly competitive abilities, which promotes its establishment and rapid spread. To explore biological traits that may explain its highly competitive abilities, we focused on expression of phenotypic plasticity in response to the food conditions experienced by the females during their development as juveniles in the invasive speciesB. xylophilusand native speciesBursaphelenchus mucronatus. We report an unexpected significant difference of phenotypic trade-off between egg number and egg size in the invasive speciesB. xylophilusand native speciesB. mucronatus. This leads to superior propagation ability of invasive species, under high and low food conditions in culture. These effects reflect adaptive optimal resource allocation where more eggs are produced in favorable environments to enhance population viability. Furthermore, we show thatB. xylophiluseggs hatched earlier thanB. mucronatuswhen their parents experienced high food availability. Thus, this study revealed, for the first time, phenotypic plasticity of reproductive traits inB. xylophiluswhich empowers the species a competitive advantage relative to their native counterpartB. mucronatuswhen they are under different range of food availability. These results are a step towards answering the vital question of how an exotic invasive species exclude a native species from its original niche.
